n WHEEL FOR VEHICLES.

To allivhomit may concern. n 1 f Be it. known that I, Ciani. Kixnsciiiziir, va

have invented certain iiewand useful Iniproveinents in'll'heels for Vehicles; and I do hereby declare the following to he a full,

V clear. and exact description ofthe invention.

VKof this kind as heretofore usuall)` constructed the canisare distributed take ofi' the removable riuiit is necessary, in

most cases, to actuate all the cams. itiirtlier-l iiiore, when the flange of the fixed rim'wliich serves as an abutment for the removable rini is forced outwardly .byprolonged running,

that istlattened toward the wheel hub, the

cams no longer bear sutiiciently upon the re n in; 'able riinto securely hold itzfast upon the fixed rim. According to the present invention these disadvantages are 'avoided by attarhnrer to the kfixed rim an axially adJust- :il-le tension or abutment pieeeavliicli ein-A bi'aces about onev'third of the wheel periphery and isA formed with an inwardly directed wedge face, and which` when the removable rim isput on and taken oft is not moved, and when the cams distributed over the remaining portion of the vperiphery are tightened up. etl'ects .the centering of the tire. wheel the flange of e the fixed rim which serves as an abutment. for the removable rim. becomes to some extent flattened so that the removable rim has to be pushed farther iiiwardly in an axial direction in order to bear against t ie said abutment flange, the tension piece is correspondiugly adjusted axially :uid the removable rim thereby so shifted u-centrically,with respect to the fixed rim or telly... that the lcams opposite this tension piece again engage siifticiently with the seit'- ably shaped edge of the removable riin as to insure secure attachment of the removable rim to the fixed rim. 'l`lie slight eccentric displacement aud any oblique setting of the removable riiu relatively to the tixed riin vor fellv which may be occasioned thereby is rendered unnoticeahle by the pneumatic tire.

l provide a tension or abutment piece e which is formed with an inwardly directed wedge face and embraces about one third of the periphery of the wheel. Around the reordinary fixed` rim a.; f

inainiiig portion of the periphery are dis tributed rotary cams f, the beveled faces of Vwhich bear against the outer edge of the re- 1movable rim and kcan be tightened up in a well known way by means ofk a key. 'hen vthe renuivable `rim carrying the pneumatic tire is to be exchanged for another one, the eanis j' are partially rotated to release the removable riiuat'ter which the portion held by the cams j' is swun.;r outward and the rim? may then be lifted ott'` in a radial direction from the middle of the tension piece in awell known manner. "lhe adjustment of a new vini can then be efl'ected in reverse manner. ln this way one pneumatic tire can be readily exchanged for another in exceedingly small time. When after prolonged use of a wheel the tlange of the fixed rim becomes .soliiei-vliat 'forced back or flattened so that 1 the ca-ms no longer grip-the removable rim as firmly as formerly the tension piece c is adjusted in an axial direct ion inwardly by the removal of the washer f/ which is interposed lwtween the inner face of the securing flangeV through which the bolt l passes and the. outer face of the. felly, or a washer of less thickness is substituted therefor and the bolt then tightened. The wedge face of the tension piece isv thereby caused to press the removable rim slightly outwardly whereby that part. ot' the rim lyingr dametrically opposite to the tension piece is corresponding yv brought nearer to the fixed rim so thatl the cams can again bear suiiiciently upon the outer edge portion of the removable rim to enable it to be firmly held. The eccentric .position of the removable' rim, and lany ,obligue position it may have relatively to the xed rim, resulting from the adjustment. of the tension piece do not, taking into considerationthe comparatively large diameter of the pneumatic tire, have any injurious use of wed-gepieces and eccentrics per se;

1 claim as my invention: In a vehicle wheel the combinationjof a removable rim having inclined outer edges wlth a 'fixed rim having an outwardly 1nchned flange, an axially adjustable tension piece having an inwardly directed Wed'fev face extending over a portion of the perip ery of the wheelvand adapted to bear against said removable rim, screwboltsfor adjusting the tension `piece and rotaryV cams arranged around the balance of the periphery against of the wheel and adapted to bear the removable rim. y Y K In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesseaf f CARL KINDSCHERF.
